Lubricating system.



E. SEARS. LUBRICATING SYSTEM. APPLICATION man SEPT. 26. 19m.

Wardly thereon and into the chamber of the shaft 3 through the cut outportions 26 on either' side of the plate-as in F ig. 1.

l During the rotation of the roller shell or' drum at high speed, thelubricant 'directed by the plate into the chamber 4 flows into the bores5, through the ports 19 and 20 onto the rollers 10, lubricatingthevsame, and

thence flows outwardly into the ports 21 and from there isforced by therotation of the n hub into the chamber 22 and through the channels 23into the roller shell or drum 15, from which place itis again picked upby the plate 25. When the roller shell or drum is ,rotating at `aslowspeed, the vlubricant passes' into the chamber 22, Athrough the.channels 23, from which -it news-.through the ports 21, lubricating therollers 10'. Lubricant which passes-between the flanges 13 and 8 isreturned. to, the chamber 22'through .the lpassages 232, and is thusprevented from passing between the shafts'l and shunts 17.'

' It will be apparent that I haveprovided alubricating system y forrotating bodies wherein there is maintained at all times during therotation of the body a-continuous flow of lubricant from the reservoirto the body bearing and backto the reservoir.

vMy' improved system yis equally as `well adapted for use in connectionwith sheaves,

belt supporting drums or the like, as it is for the pantograph rollerconstruction em y with the interior'of the hub, and a shell carried bysaid hub and adapted to contain a quantity of fluid lubricant, theinterior chamber of said shell being in communication with said radiallyvdisposed. channel in said hub.

, 2. In a device of the class described, `the combination with a tubularsupporting shaft formed with a fluid inlet and a 'fluid outlet, a hubrotatably mounted on said shaft over 'said fluid outlet, and a radiallydisposed open ended channel therein, a hollow member carried by said huband adapted to contain a quantity of fluid lubricant, bearingsinterposed between the hub and said shaft, and a baffle in said fluidinlet and projecting outwardly from said shaft.

3. An oiling system for rotary bodies comprising a tubular supportingshaft formed with a fluid inlet and a plurality of fluid outlets,supporting hubs rotatably mounted on formedwith a Aradially disposedopen ended said shaft over said'fluid outlets, and each.

channel therein, the outer ends of said channels opening at adjacentsides of the respecf chamber and a longitudinally disposed slot,

1n the upper wall thereof communicating with thecirculating chamber,said shaft also provided with a fluid outlet extending therefrom, a hubrotatably mounted on said shaft ,over said fluid outlet and fixed withinthe interior of the said shell, said h ub being formed with a radiallydisposed channel having its ends in registry respectively with saidfluid outlet and the said fluid containing chamber, and a baffle fixedto said shaft and extending upwardly therefrom todirect the fluid intothe longitudinally disposed slot thereof.

5. 'A lubricating system for the described purpose comprising arotatable shell provided with an interior| fluid containing chamber, ahollow shaft within said chamber, provided with an inlet in the' wallthere` of communicating with the interior of the chamber 'and a fluidoutlet, a hub rotatably mounted on said shaft, fixed to saidshell, andformed with radially disposed channels communicating at their inner endswith the interior bearing surface of said hub and at their outer endswith the said fluid containing chamber, bearings interposed between saidhub and' said shaft for maintaining the relative radial and axialpositions thereof, and means carried by the said shaft for directingfluid therein through its inlet opening.

6. A lubricating system for rotary bodies comprising a fixed supportingshaft provided with a central longitudinal circulating chamber having anaxially disposed fluid inlet and radially disposed fluid outlets, a

hub rotatably mounted upon said'shaft Vover said fluid outlets, saidVhub being formed with a radially disposed open ended channel, ahollow-member carried by 'said hub and adapted to contain a quantity offluid lubricant, and means for directing a flow of the lubricantcontained therein into said axially disposed fluid inlet of thesupporting shaft. v y

7. A lubricating systemA for rotary bodies comprising a` pair of .xedalinedsupporting shafts provided with central longitudinal circulatingchambers having axially disposed fluid inlets atv their adjacent endsand radially disposed duid outlets, supporting hubs rotatably mounted onsaid shafts over' said fluid outlets, and each formed with a radiallydisposed open ended channel therein, the outer ends of said channelsopening at adjacent sides of `the respective hubs, a tubular membercarried by and closed at its ends by said hubs and adapted to contain aquantity of fluid lubricant, and means within said tubular member forintroducing the fluid lubricant -contained therein into the said axiallydisposed fluid inlets of the chamberedaxle shafts.

8. A lubricating system for rotary bodies comprising a pair of fixedalined supporting shafts provided with central longitudinal circulatingchambers having axially disposed openings at their adjacent ends andradially disposed uid outlets, a tubular shaft connecting the adjacentends of said supporting shafts, and provided with fluid inlet openingsin the peripheral wall thereof, supporting hubs rotatably mounted onsaid shafts over said fluid outlets, and each formed with a radiallydisposed open ended channel therein, the outer ends of said channelsopening at adjacent sides of the respective hubs, a hollow7 membercarried by and closed at `its ends by said hubs and adapted to contain aquantity of fluid lubricant, and means within said hollow member fordirecting a flow of the fluid contained therein into the saidfluid inletopenings in the tubular connecting shaft.

9. A' lubricating system for the described purpose comprising .a fixedtubular shaft provided for a portion of its length .with a bearingsurface, a shoulder adjacent to said bearing surface, a fluid outletopening from the interior chamber at said bearing surface, and a fluidinlet opening at another place in said shaft; a hub rotatably mounted onthe bearing surface of said shaft, and provided with a radially'disposed channel leadying from the inner bearing surface of the hub toan outlet near the. periphery thereof, an axial bearing surface 011 theface of said hub to engage the shoulder on said shaft, an annularextension from the face of the hub to inclose the said axial bearing,and a fluid outlet opening in said face to transfer fluid from Withinsaid annular extension to the radially disposed channel of said hub; ashell carried by said hub, surrounding the said tubular shaft, andforming a fluid containing chamber, said chamber being in communicationwith the fluid inlet opening in said shaft and the outer end of theradially disposed channel in said hub; and means within said chamber forinducing a circulation of the fluid therein contained through therespective channels of said shaft and said hub.

In testimony -whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWARD SEARS.
